Eight less than two-fifths of the seventh grade students had a perfect attendance in the first quarter. If 142 students had perfect attendance, how many seventh grade students are there?

the number if seventh grade students is 375

Step-by-step explanation:

Let x represent the number of seventh grade students are there.

Eight less than two-fifths of the seventh grade students had a perfect attendance in the first quarter. This means that the number of students that had a perfect attendance in the first quarter is

2x/5 - 8

If 142 students had perfect attendance, it means that

2x/5 - 8 = 142

2x/5 = 142 + 8 = 150

2x = 150 × 5 = 750

x = 750/2

x = 375

easy math just plug in a and b

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
